Drilling Holes Line Opportunity's Path
This image composite shows 11 holes dug by the Mars Exploration Rover Opportunity's rock abrasion tool into the slopes of "Endurance Crater." The main panoramic camera image highlights more recently made holes (yellow) and the rover's path into the crater (pink). The navigation camera image to the right shows the first seven holes drilled into Endurance. Each hole is 4.5 centimeters (1.8 inches) in diameter.
